Extreme packet loss - jitter

Has anyone else has extreme packet loss and jitter. My internet is almost unusable. Packet loss around 10% on average. Which makes VOIP and skype calls for work unusable and I like to game also so can't play.

I'm being pushed back and forth between TPG and NBN co. Had to take two days of work to be at home for both to do test which proved the same thing. There has been no urgency on trying to help with the issue and would appreciate so much anyones help.

I've done so many ping tests to prove the jiter and packet loss to prove the issues not from inside the house but past the modem.

I have an NBN tech who has just been to report once again that there is no issue from their end at the house. After i told the tpg engineering team that i am wasting my time. This is the last time I will be taking time off work to be at home. I’ve lost over $1000 in wages now.I also told them it’s pointless sending them at these hours as there is normally no issues. The issues are between 5-10pm where it is unusable for what I require. Packet lost of between 10-20% and upload of 1mbps. As they remove your existing phone line you are now expected to use VOIP. But you can’t use VOIP with packet loss and jitter as your voice is a robot and you only hear every 4th word.I would expect and I’m more than happy with loss of speed during peak hours as this is to be expected. But there should be no packet loss and jitter as I’m receiving.
